The big problem appears to be that there is only one kind of connection
per port, so the buffer munging code can't distinguish between output and
input connections (obviously there was no need before).
I'm about to embark on splitting up the connections lists into input_ and
output_connections, so shout now if there are likly to be any showstoppers
(eg. I'l let you commit that over my dead body ;)
God bless CVS,
Steve
